Nsgarsh,like you I am already "blown away" with how superb,already, the "underated" Trannies can perform.Of course that would consist of an arm that was NOT "sibilent",as it would destroy the magic.-:)Since both our arms are not of the "sibilent" variety-:)we have nothing to worry about!Heh,heh!(stroke of my moustache).
In all seriousness,I too have the Boulez performance you mention,and it is a "corker"!I have at least a half dozen Firebirds,and can really recommend the early pressing Mercury with Dorati,for the incredible double basses in the opening movements.Warmth and power at the same time,along with a huge,wide stage,that the Mercury pressings were famous for.I'm talking real/gorgeous/almost scary tonal balance,when "right".We're talking midbass resolution,as opposed to deep bass power,which is there too.BTW,the Speakers Corner Reissues are superb,but an early original has better tone color,across the board.That is why we love the "super cartridges".They can portray this clearly.Hard to quantify the difference between the "great cartridges" if you make a steady diet of heavy metal,and rock,though some of that stuff is loads of fun.I could never bring myself to getting rid of my rock collection.
I do look forward to your future comments,Larry.Take you're time.It will probably take a good few weeks for breakin and revoicing.Don't feel pressure to post quickly,just to satisfy "nuts" like me!Just do it soon -:)
I do know that the Trannys are considered in the highest echelon of designs,in some quarters,but they haven't caught on for a long haul in the U.S.I hope that is NOT one reason for a new model,but I'm always suspicious of newer models.One reason why I never warmed up to the Eidolon speaker,after living with my Ascents.
Sorry for the rant.
Best!
